CAR-BRAKE.

SPECIFICATION forming part of Letters Patent No. 241,079, dated May 3, 1881.

Application filed October 30, 1880.

To all whom it may concern Be it known that we, UARL FREDRIOK SINN and WILLIAM STUDER, both of the city of Montreal, in the district of Montreal and Province of Quebec, Canada, have invented certain new and useful Improvements in Railway- Brakes; and we do hereby declare that the following is a full, clear, and exact description of the same.

Our invention, which is especially applicable to freight-trains, is intended to obviate the difficulty which has hitherto been found in applying continuous brakes to such trains, the cars of which are usually of different construc tion and heights, and coupled together in such a way that the distance between them constantly varies. The mechanism which we have invented for this purpose provides a continuous brake acting simultaneously on the wheels of all the cars, operated from any part of the train either by the ordinary hand-lever or any other power, and taking up the whole slack gf the train before bringing the brake-shoes to ear.

Our invention may be briefly described as the arrangement immediately above the truck of the wheels to which the brakes are applied of two sheaves carried in a frame hung from and running along a bar or traveler secured under the car. Round one of these sheaves is taken a chain, one end of which is secured to and wound on the hand-brake and the other attached to the end of a rod carried in suitable hanger passing out under the draw-bar, and provided with means-such as a hook and snap, &c.--for connecting it with the corresponding rod of the next car. The other sheave has also taken round it a chain, one end of which is secured to the brake-lever and the other connected to a rod which, carried in suitable hangers, passes along and out centrally at the other end of the car.

For full comprehension, however, of our invention reference must be had to the annexed drawings, in which- Figure l is a plan, looking upward, of the invention as applied to a car, the brakes bemg off; and Fig. 2, a longitudinal sectional elevation of the same with the brakes on.

(No model.)

Similar letters of reference indicate like parts.

The construction and arrangement of the trucks, wheels, axles, and brake-beams, with their levers and shoes, may be of any approved kind, and need not therefore be further described.

A is a frame, provided with an eye, A, and thereby hung from and sliding upon a bar, B, secured to the car. In this frame are carried the ends of the spindles c and d of the sheaves 6o 0 and D. Round the sheave (J is taken the chain E, secured at one end to the hand-brake F, of any suitable construction, and with its other end fastened to the rod G, provided with shoulder G upon it, carried in hanger H out 6 beyond and under the draw-bar, and having secured to its loose end any suitable device, such as is shown, by which it may be connected with the COIICSPOl'ldillg rod of thenext ear. Round the sheave D passes, as shown, the chain I, with one end attached to the end of the brake-lever and the other to the rod K, (also provided with shoulder K,) carried out under the draw-bar, and having connecting device.

The operation of our invention is as follows:

In the car on which the brake is applied its rotation will wind upon it the chain E, thereby drawing equally both on this chain and the chain I, and pulling in both directions until the full amount of the slack through the train has been taken up. As soon as this is done all the brake -shoes will be simultaneously brought in contact with the wheel-tires.

The operation of our invention in those cars which are acted upon from the car in which the brake is put on is very simple. Either of the rods G or K, and through these respectively the chains E or I, will be drawn upon until the full amount of slack, as before de- 0 scribed, is taken up, and the brakes then immediately put on. The brake 1 in this instance, simply serves as a point of attachment for the end of the chain E.

The shoulders G and K, bearing respectively against the hangers l1 and H, while allowing the full amount of slack to be taken up, act as stops, and in the last car of the train s prevent the rods from being drawn through chain or rope with a hand-brake or fixed point, and a rod passing out beyond the other end of the car and connected by a rope or chain with the brake-lever, each of these chains or ropes passing over a separate sheave, both sheaves 20 being carried in a sliding hanging frame, all substantially set forth, and for the purposes described.

Montreal, 20th day of October, A. D. 1880.
